Extremely Low-Frequency Electromagnetic Fields Promote In Vitro Neuronal Differentiation and Neurite Outgrowth of Embryonic Neural Stem Cells via Up-Regulating TRPC1. [PDF]

PLoS ONE, 2016
Exposure to extremely low-frequency electromagnetic fields (ELF-EMFs) can enhance hippocampal neurogenesis in adult mice. However, little is focused on the effects of ELF-EMFs on embryonic neurogenesis.

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

Advanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Ga‐on‐In Substitution with Zn Vacancies in Zn3In2S6 Induces Electron–Hole Asymmetry and In─O Bond Weakening for Coupled Two‐Electron Oxygen Reduction and H2O2 Stabilization

Advanced Materials, EarlyView.
Ga‐on‐In substitution coupled with Zn vacancies in Zn3In2S6 creates a dopantdefect synergy that weakens InO bonding and induces electronhole asymmetry. The resulting spatial charge separation directs the two‐electron oxygen reduction pathway, enabling efficient artificial photosynthesis of H2O2 with a production rate of 187.8 µmol g−1 min−1 ...

Environmental evaluation and employee’s exposure of a thermal power plant with extremely low frequency magnetic fields

Salāmat-i kār-i Īrān, 2015
Background and aims: Extremely low frequency magnetic field (ELF) is part of Spectrum of electromagnetic waves with range 30 to 300 Hz. The average magnetic field exposures in the workplace have been found to be higher in “electrical occupations” than in

Extremely low-frequency magnetic exposure appears to have no effect on pathogenesis of Alzheimer's disease in aluminum-overloaded rat. [PDF]

PLoS ONE, 2013
OBJECTIVE: Extremely low-frequency magnetic field (ELF-MF) has been reported to be of potential pathogenetic relevance to Alzheimer's disease (AD) for years. However, evidence confirming this function remains inconclusive.

Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis

Advanced Science, EarlyView.
SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...
